No, ESCs are calibrated before shipping. They only require calibrating if you replace one of the ESCs or motors.

You need to recalibrate the sensors when you receive your drone and when you move location (more than 40 km / 24.8 mi from your last location). This is due possible changes in temperature, altitude and magnetic declination. We recommend you to first recalibrate the accelerometer and after the compass. In this specific order.

Only recalibrate the drone once you have arrived to the area where you will fly your drone in.

If you have received the controller in a separate shipment than the actual drone shipment, the transmitter is not yet paired.

To do so, you will need to follow the steps mentioned in the user manual of the drone, or read the FAQ section on the website to read how you can bind the controller to your receiver.

Always remember to import the model of your drone before binding them together.

Here are the steps for binding the RX8R Receiver:

**During this process keep the transmitter at least 1.5 meter (3.28 ft.) away from the receiver.

Power-off your drone
Press and Hold the F/S button on the receiver (Do not let go of this button!).

Then power-on your drone while still holding this button.
It should now go into bind mode, showing a solid red and green LED once it is in bind mode.
You can now let go of this button.

Power on your transmitter, make sure the correct model is selected ( * beside the name)

Press the page button and scroll down to the Mode option. and select ACCST D16 then scroll down to receiver and click on Bnd,

Then select CH1-8 Telem OFF

Once you have completed the previous steps, your remote controller should start making a chirping sound. Your receiver should start blinking the red LED.

After this, on your controller, press “exit” multiple times until you are on the main screen. You can now reboot your drone (disconnect and connect the power).

The LED should now show solid green on the receiver. 

You have just completed the binding of the receiver.

You can test the motors one-by-one, using the Mission Planner software. It's explained using the image below.

In this example we have used a 4 rotor drone. That's the reason why you only see a 'Test motor A to D'. In case you would have your drone connected and it has 6 or 8 rotors, it will show you motor options such a motors A to F (6 rotors) or motors A to H (8 rotors). 

Before testing, it is highly recommended to remove all propellers.

Your front right motor is motor "A". Continuing from there in clockwise direction, you have motor B, C, D and so on depending on the amount of motors you have on your drone.

See the exact letters and motors in the images below. 

• Go to "SETUP" in Mission Planner
• Then go to "Optional Hardware"
• Then go to the section 'Motor Test'
• Set throttle to 10% and duration 2 seconds
• You can now start testing the motors as you see in the image. You can check if the order and the spin directions of the motors are correct.

To always be informed about the full take-off and landing procedures, always first read the manual about different flight modes and their behavior.

For take-off with the drone’s first flight we recommend being in Loiter Flight mode. After arming, move to 50% throttle and your motors will start to spin, but the drone won’t take off yet. Now move the throttle to 75-85% to have a quick take off.

Once taken-off, move the throttle back to 50% and hold the drone’s altitude at 1.5 or 2 meters (5 or 6.5 feet) above the ground to test the drone’s movements in all axis.

Note:
If something doesn’t look right, land the drone and contact our customer support.

There are two ways to get the flight logs:

• SD Card
• Ground Station

Retrieving Logs from SD Card
There is an SD card inserted in your drone's Flight controller. You can remove that SD card and copy all the information into a zip file to send that to us.

Retrieving Logs from Mission Planner
Mission Planner allows you to download the Flight Logs when having your drone connected via USB. To do so, you will have to connect your drone to Mission Planner and select in the "Data" Screen, on the left-hand side, the tab that says "Data Flash Logs".

Once in that tab, please select "Download Data Flash Logs Via MavLink".
After this, select the Flights Logs you want to download.

With the image on the side, it shows you the step-by-step guide through Mission Planner on how to be able to download your flight logs 

• Click on 'Data' in the top left section in Mission Planner
• Click on the arrows to the right until you see the section 'Data Flash Logs'
• Click on 'Download Data Flash Logs via Mavlink
• A pop-up will come up where it will show you all flights logs of your connected drone. In case you want to download all flight logs, you can skip this step and go to '5'.
  
  In case you want to download specific flight logs, select each individual flight log you want to download here.
• In case you want to download all flight logs, click on 'Download All Logs'.
  
  In case you have selected separate flight logs, for instance the 5 specific you want to download, click on 'Download Selected Logs'.

Your Flight Logs will now begin to download.

NOTE: your logs will be saved to  your computer on the Log Path set on this screen

For us to be able to give the best and most effective support possible, we recommend to send us the Flight Logs of your drone.

What's even more helpful in case of a crash, is that see any video recording of the drone flying when the incident occurred, photos of the drone prior to the crash and after the crash and a detailed description of what happened.

Please always include the serial number of your drone when sending us your information.

We recommend using Mission planner. Mission Planner a constant evolving open-source software and has been the go-to software of choice due to that.

Mission Planner is the software we most commonly use throughout our offices for the drones we manufacture, have the most experience with and therefore making it even easier to give you support.
